I have this problem sometimes with a few other programs. I have Windows XP. Windows XP shares drivers/files with multiple programs and sometimes when a person uninstalls a program they unintentially deleate a file in a different program causing that program not to work correctly!

I suggest reinstalling Limewire and hopefully that would work? Or type the fatal error on google to find what exactly the problem is? Last you could do a system restore from before the problem occured, but you might want to back-up your files to cd first!

I do a system restore point before and after I install/uninstall a program just to be on the safe side...

Cheers
